20.500.12556/RUL-188865 Sistem za vsebinsko odzivno osvetlitev ozadja zaslona Content-responsive display back-lighting system V diplomskem delu smo razvili celovit sistem za vsebinsko odzivno osvetlitev ozadja zaslona. Sistem barve prikazane vsebine na zaslonu preslika na naslovljivi trak LED, nameščen na zadnji strani zaslona, kar ustvari vtis nadaljevanja slike prek njegovih robov. Sistem je namenjen uporabi med predvajanjem video vsebin ali igranjem računalniških iger, zato sta bili glavni zahtevi hitro sledenje prikazani vsebini in majhna poraba sistemskih virov. Programski del sistema zajema sliko zaslona. Sliko nato zmanjša in iz nje določi barve posameznih diod LED. Izračunane barvne vrednosti najprej prilagodi za boljše ujemanje barv osvetlitve z barvami vsebine na zaslonu, nato pa jih prek povezave USB pošlje mikrokrmilniku, ki jih pretvori v podatkovni signal za krmiljenje traku LED. Sistem podpira tudi analizo zvoka in prikaz svetlobnih učinkov, usklajenih z ritmom glasbe. Sistem smo razširili še s programskim vmesnikom, ki zunanjim programom omogoča direktno krmiljenje svetlobnih učinkov. Uporabo programskega vmesnika smo prikazali z demonstracijsko igro v okolju Unity, v kateri se osvetlitev odziva na svetlobne vire in dogodke v igri. Poleg traku LED in njegovega napajanja dodatna strojna oprema sistema obsega mikrokrmilnik za krmiljenje traku LED. Osvetlitev dovolj hitro sledi prikazani vsebini tudi pri preizkusih z igrami, ki grafično procesno enoto obremenijo do polne zmogljivosti. Zmogljivost igre se zaradi dodatne obdelave zmanjša za približno 6 %, kar smo ocenili kot sprejemljiv vpliv. S prilagoditvijo barvnega odtenka, nasičenosti in svetlosti dosežemo boljše ujemanje med barvami na zaslonu in osvetlitvijo stene. Končne ugotovitve potrjujejo, da smo dosegli vse zastavljene cilje. In this thesis, we developed a complete system for content-responsive display back-lighting. The system maps colors from the displayed content to an addressable LED strip mounted on the back of the display, creating the impression that the image extends beyond its edges. The system is designed for use while watching video content or playing computer games, so the main requirements were fast response to changes in the displayed content and low usage of system resources. The software captures the screen image, reduces its size, and determines the color of each LED. The calculated color values are first adjusted to improve color matching between the lighting and the displayed content. Values are then sent via USB to a microcontroller, which converts them into a data signal for controlling the LED strip. The system also supports audio analysis and lighting effects synchronized with the rhythm of the music. We also extended the system with an application programming interface that allows external programs to directly control the lighting effects. We demonstrated its use with a demonstration game developed in Unity, in which the lighting responds to light sources and in-game events. Apart from the LED strip and its power supply, the additional hardware component is the microcontroller for supervising the LED strip. The lighting responds quickly enough to displayed content even in tests with games that fully load the graphics processing unit. Game performance decreases by approximately 6 % due to the additional processing, which we considered acceptable. By adjusting hue, saturation, and brightness, we achieve a better match between on-screen colors and the lighting on the wall. Final findings confirm that all objectives set for the system were achieved. vsebinsko odzivna osvetlitev naslovljivi trak LED zajem zaslona obdelava slike analiza zvoka mikrokrmilnik programski vmesnik content-responsive lighting addressable LED strip screen capture image processing audio analysis microcontroller application programming interface true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-29 13:55:01 2026-09-29 13:55:11 2026-09-30 04:29:23 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 38762 Knez_Matic_-_Sistem_za_vsebinsko_odzivno_osvetlitev_ozadja_zaslona.pdf Knez_Matic_-_Sistem_za_vsebinsko_odzivno_osvetlitev_ozadja_zaslona.pdf 1 61DCFA9E609C0858082E56C9DFAC4ACC ab94773d4c3ccfd3a6e594604086a00611652f62f4abaffa58e5aa433eb297fe 869d8c98-bbfc-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=249239 Fakulteta za računalništvo in informatiko 0 0 0
